One to One! Russian talent show based on the Spanish series Your Face Sounds Familiar. The show involves celebrities (actors, television personalities, comedians) portraying various iconic singers each week.
The show challenges celebrities to perform as different iconic music artists every week, which are chosen by the show's "Randomiser". They are then judged by a panel of celebrity judges. Each celebrity becomes transformed into a different singer each week, and performs an iconic song and dance routine well known by that particular singer. The 'randomiser' can choose any older or younger artist available in the machine, or even a singer of the opposite sex
